Application mea Karen 31.1928. serial No. 266,408.

This invention relates to centrifugal -extractors and particularly relates to the lbaskets of such extractors.

Another object is to provide an improved drive mechanism for the basket of an extractor permitting an easy and expeditious removal of the "basket from the curb. and its replacement therein. v

'Still another object is to provide an exl tractor basket with a pair of doors permitting a complete uncovering of the basket bottom, upon removal of the basket from the curb.

A still further object is to form .the bottom of an extractor basket by a pair of hinged doors and to mount upon one of said doors a socket v member for driving the basket and centrally supporting it within an extractor curb.

It is also an object of the invention to provide an improved means for latching in its closed position-a door formed in the bottom of an extractor basket.

These and various other objects the inventionattains by the construction hereinafter described andI illustrated in the accompanying drawings, wherein:

vIn these `views the referencev character 1 designates the curb of an extractor, formed preferably of cast iron. For the purpose of this invention said curb may be mounted in.

any suitable manner, but it is preferred, for reasons hereafter set forth, to suspend said curb by a plurality of bars 2 extending upwardly at a slightly outward inclination from the curb bottom andhaving their upper extremities respectively mounted in suitable posts 8. As best appears in Figure 2, the4 engagement of said bars with said curb `and posts is such as to afford the curb a slight lateral movement in any direction. In the curb bottom there is centrally formed an opening .4 through which freely passes a vertical drive shaft 5 provided beneath the curb with some suitable power transmission ele.-

ment, as for example, a sprocket wheel 6 engageable by a drive chain 6. Said shaft is journaled interiorly of the curb in a. bearing member 7 secured to the curb bottom by bolts 8 or other suitable means. Said bearing member is exteriorly conically tapered and is interiorly yprovided with anti-friction bearing elements 9 mounting said shaft. The latter has a portion 10, pro]'ecting above the bearing member 7 and gradually tapered to provide a mounting for a driving member 11. Said member preferably is formed with a skirt portion 12 which surrounds the bearing vmember 7, as clearly seen in Figure 2. The

bearing 11a is arranged between the top f ace of the bearing member 7. and the driving member 11. The latter is clamped upon the shaft 5 one or more nuts 13 engaging a stud 14 formed upon the upper end of said shaft. Within the curb 1, in spaced relation to its side wall and bottom, is centrally mounted a basket 15 comprising the usual perforated circular wall formedy of sheet metal or the like, exteriorly reinforced by hoops 16 and further interiorly reinforced by rings 17 and 18 riveted respectively to the top and bottom portions of said wall. The bottom of the basket is formed by a pair of substantially semi-circular doors 19 and 20, oppositely hinged to the ring 18 therebeneath as indicated at 21, and adapted in closed position to seat against said ring. The free edges of said doors are adapted to meet, in their closed position, in an approximately diametrical relation to the basket and preferably the door 20 is formed with a marginal lip 22 which overlaps a similar lip 23 on the door 19.

For rotatively mounting the basket 15 and establishing a drive thereto from the member 11, it is preferred to integrally form upon the door 19 a socket member 24, which in the closed position of the doors projects centrally upwardly within the basket and is adapted to fit snugly over the drive member 11, interiorly conforming to the latter. Thus the basket is entirely free to be lifted from the curb and out of driving engagement with the member 11 or to be lowered into such engagement, and the substantially conical formof said socket and driving members facilitates such engagement and disengagement. While the frictional contact between the parts 11 and 24, is under most circumstances adequate to transmit thefdesired drive, 1t 1s preferred to provide a number of spline ways 25 in the drive member 11 to receive spllnes 26 interiorly secured to the member 24 and preferably said spline ways and splines are of the wedge shape, best illustrated in Flgure 8, so as to facilitate their mutual engagement and disengagement. It will be noted that the door 19 has a semi-circular .projection 28 from its free edge to afford an adequate support for the socket member I 24, (see Figure 3) the door 20 having a corresponding -semi-circular opening at its free edge.

For locking the doors 19 and 2O in ltheir closed positions, there is associated with each door a air of latch mechanisms oppositely carried y the ring 18 and engageable with opposite points of the doors adjacent to the free edges thereof. Each of these mechanisms comprises a latch bolt 29 radially slidable in the ring 18 and engageable in a socket 30 formed in a lip 31 marginally upstandin g upon the correspondingdoor. A pin 31B duplicating the bolt 29 is similarly slidable in the ring 18 above said bolt, said bolt and pin being Arigidly connected by a coupling member 31'b and said ring having a chamber 32 opening in 'its inner face to accommodate said coupling member. A closure 33 for the chamber 32 is suitably secured to the inner face of the ring 18 and between said closure andthe coupling member 31", springs 34 are coiled upon the pin 31a and bolt 29 urging the latter to its locking position shown in full lines in'Fig. 7. For retracting said bolt, a lever 35 is mounted in a circumferentially extending channel 36 in the exterior face of the ring 18 and is intermediately pivoted upon a pin 37 vertically secured in said ring.

Y At one extremity, the lever 35'bears freely upon the outer end of the pin 318L and is adapted to effect a retraction of said pin upon being shifted to the dashline position illustrated in Figure 10. To permit swinging of the pin-engaging end of said lever, the depth of that portion of the channel 36 which receives said end of the lever is increased as V indicated at 38 in Figure 10. The other end yportion of said channel is enlarged and increased in depth as indicated at 39 -to permit the fingers to grip and operate the lever. Normally, said lever is retained in the /channel 36 by the thrust transmitted tosaid lever through the pin 3.1a from the springs 34. When saidlever is swung to its dash line position, the pin 31a, bolt 29, and yoke member 31b are retracted as al unit, as is indicated lin dash lines in Figure 7, whereby said bolt is withdrawn from the socket 30, permitting the corresponding door to drop. Thus the doors may be separately released, so as to permit a full or a partial opening of the bottom of the basket.

Inithe use of the described extractor, after completionof an extracting operation,the basket 15 is lifted outvof the curb 1 by any suitable mechanism and conveyed to any point where it is desiredto Adischarge the contents of said basket. At such -point the latch mechanisms controlling the doors 19 and 20 are operated to release said doors, allowing them to drop to the open position shown in Figure 5, and thus permitting a free and unobstructed discharge of the contents of the basket. The doors are then again closed and latched, and the basket is replaced in the tub for further use.

An important yfeature of the construction is the provision made for very quickly removacting socket member 24, and also from the avoidance of any rigid connection between the basket and its drive member.

By adapting the curb 1 to undergo a slight..

as carried b v one of the bottom-forming doors 19. 20. it is to` be understood that the features of providingdoors in the bottom of the basket to facilitate discharge of the basket and of adapting'the basket to be readily removed from the curb do not necessarilyy requireuse of one of said doors as a carrier for the driving and the supporting socket member.

Also, while it will be apparent'that the illustrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages primarily stated itis to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.
